提交表格（无模型）并且无法让控制器发挥其作用 [英] Submitting a form (no model) and having trouble getting the controller to play its part

问题描述

我为webapps创建了一个基本框架（一些静态页面，用户认证，rspec的单元/集成测试）。我想用这个作为未来webapps的基础，但是我需要设置一个方法，在从github克隆它之后重命名它。我在这里获得了一些帮助来生成重命名的代码]，但我正在努力弄清楚如何整合它。

I’ve created a basic framework for webapps (some static pages, user authentication, unit/integration testing with rspec). I’d like to use this as a foundation for future webapps, but I need to setup a way to rename it after cloning it from github. I got some help generating the renaming code here]1, but I'm struggling to figure out how to integrate it.

我原来写了rakefile中的重命名代码，但现在我想可能它应该在控制器中。不幸的是，我一直无法让我的代码工作。我有一个允许用户为应用程序输入新名称的视图。这个想法是，用户将克隆框架回购，CD到框架目录，启动rails服务器，然后去他们的浏览器本地主机重命名从那里的文件。但假设启用该视图的视图不起作用。

views/namer/new/html.erb <h1>Rails Framework</h1> <%= form_tag "/namer" do %> <%= text_field_tag "appname" %> <%= submit_tag "Name Your App" , :action => 'create' %> <% end %>

I can't get the "submit" action to work to work properly.  Here's what my controller looks like.

我无法使提交操作正常工作。这是我的控制器的样子。

controllers/namer_controller.rb class NamerController < ApplicationController def index render('new') end def new end def create @appname = Namer.new(params[:appname]) #first, change any instances of the term "framework" to the new name of the app file_names = ['config/environments/test.rb', 'config/environments/production.rb', 'config/environment.rb'] file_names.each do |file_name| text = File.read(file_name) File.open(file_name, "w") { |file| file << text.gsub("Framework", @appname) } end #next,change the root path away from namer#new file_name ='config/routes.rb' text = File.read(file_name) File.open(file_name, "w") { |file| file << text.gsub("namer#new", "pages#home") } flash[:notice] = "Enjoy your app." render('pages/home') end end

Any idea what I'm doing wrong?

任何想法我做错了什么？

Also, it the controller really the best place for the "renaming" code?

另外，它控制器真的是重命名代码的最佳位置？

edit: here's my routes.rb file.

编辑：这是我的routes.rb文件。

Framework::Application.routes.draw do resources :users resources :sessions, :only => [:new, :create, :destroy] match '/signup', :to => 'users#new' match '/signin', :to => 'sessions#new' match '/signout', :to => 'sessions#destroy' match '/contact', :to => 'pages#contact' match '/about', :to => 'pages#about' match '/help', :to => 'pages#help' root :to => "namer#new" match ':controller(/:action(/:id(.:format)))'

UPDATE: I've changed my code in a few ways. 

更新：我用几种方法更改了我的代码。

创建一个更名模型。 Models / renamer.rb只是类别名称，然后是结束。 （我删除了< Base :: ActiveRecord，因为没有涉及数据库。）

为重命名代码创建了一个rake文件。它只是叫做renamer.rake。

1. Routes: added post '/namer' => 'namer#create'
2. Created a Renamer model. Models/renamer.rb is just "class Namer" and then "end." (I removed the "< Base::ActiveRecord" because there's no database involved.)
3. Created a rake file for the renaming code. It just called "renamer.rake".

事情看起来不错，但我仍然在寻找一种叫耙来自控制器的文件。任何建议？

Things are looking good, but I'm still looking for a way to call the rake file from the controller. Any suggestions?

更新2：这是我的控制器修改后的Create方法。

UPDATE 2: Here's my revised Create method for my controller. Now the renaming code is here instead of in a rake file.

def create
  @appname = Namer.new(params[:appname])
  file_names = ['config/environments/test.rb', 'config/environments/production.rb', 
    'config/environment.rb']
  file_names.each do |file_name|
  text = File.read(file_name)
  File.open(file_name, "w") { |file| file << text.gsub("Framework", @appname) }
  flash[:notice] = "Enjoy your app."
  render('pages/home')
 end

推荐答案

您的路线文件没有名称的发布匹配，看起来像。

Your routes file doesn't have a "post" match for namer, looks like. Easiest way to rectify that would be to put this line in somewhere.

post '/namer' => 'namer#create'

form_tag helper默认创建一个 post - 方法形式，如果你正在创建一个资源，那就是你想要的 - 你只需要确保你的路线在那里。有可能Rails不会通过底层的catch-all路由发送POST动作，但最好确保你的路由以某种方式命名。

The form_tag helper defaults to creating a post-method form, and if you're creating a resource, that's what you'd want — you just need to make sure your route is there for it. It's possible that Rails doesn't send POST actions through the catch-all route at the bottom, but it's much better practice to ensure your routes are named somehow.

就个人而言，只要可能，我更喜欢足智多谋的路线请在这里阅读;我承诺这是值得的。

Personally, I prefer resourceful routes whenever possible. Read up on them here; I promise it's worth it.

（如果这没有帮助...可以检查 def中的代码是否创建函数实际上正在触发？放在调试器行或放在 puts 语句中查找。）

(If this doesn't help… can you check to see if the code in your def create function is actually firing? Drop in a debugger line or a puts statement to find out.)
